Abstract

A fuse circuit (11) having a plurality of terminals (22, 23) provided on a common joint plate (21) and a fuse circuit (11′) having a plurality of terminals (22′, 23′) provided on a common joint plate (21′) are incorporated into a housing (12), thereby constituting a fuse link assembly (10). The plurality of fuse circuits (11, 11′) are provided with circuit connection portions (27, 27′) which share a power input portion. The fuse circuits (11, 11′) are incorporated into the housing (12) in parallel. As a result, the number of circuits is increased, by means of only enlargement of widthwise direction Y which is easy to increase while enlargement of longitudinal direction X stemming from packaging of circuits is minimized.

Claims

1. A fuse link assembly comprising:

at least two fuse circuits, each having a plurality of terminals, a common joint plate and a circuit connection portion, the terminals being be arranged longitudinally in a chain manner and connected to the joint plate with fusible portions; and

a housing in which the fuse circuits are mounted;

wherein the fuse circuits are mounted in the housing in parallel with each other and share a power input portion.

2. The fuse link assembly according to claim 1, wherein the plurality of terminals are removed in accordance with presence of circuits to be connected to the terminals.

3. The fuse link assembly according to claim 1, wherein the housing on which the fuse circuits are mounted is configured so as to be directly connectable to a relay box main body.

4. A layout method for a fuse link assembly comprising the steps of:

providing at least two fuse circuits, each having a plurality of terminals and a common joint plate, the terminals being be arranged longitudinally in a chain manner and connected to the joint plate with fusible portions;

providing with a circuit connection portion sharing a power input portion;

fastening the circuit connection portion together; and

mounting the fuse circuits in the housing in parallel with each other.
